Now the intro has changed, I'm unsure what you are asking for. If you need funding, either bootstrap or find a co-founder who has the social capabilities you need to raise funds. Bootstrapping is lot easier IMO, and carries less risk. If you are funded and want to market/sell your product, get a sales person (part time, perhaps). Cold calling (whether by email or phone) requires a specific set of skills and very thick skin. If that's not you, delegate. If you have no choice but to cold-email, use Linked In so that they are targeted and get a marketing person's advice on how to phrase those initial contacts so you have a good hook. (NB all the above is generic business startup advice, the same advice applies to anyone: identify the critical weaknesses; backfill from elsewhere.
